realtek: eth: Use right helper for SKB cleanup

There are two helpers to cleanup SKBs that call iternally
dev_kfree_skb_any_reason() but with different error codes.

- dev_kfree_skb_any() reason SKB_DROP_REASON_NOT_SPECIFIED
- dev_consume_skb_any() reason SKB_CONSUMED

The driver does not distinct between the two. Change this and
clean up a SKB that was handed over to the hardware with
dev_consume_skb_any(). This way kernel knows that everything
went well.
